An impact of an asteroid strike would be damage to the ozone layer. The vitality bestowed to the atmosphere by the approaching object would be sufficient to disturb the defensive layer of ozone high within the stratosphere.
Glad to help ya!! :)
Just got it right! Hope this helps!
A massive asteroid impact would create long-term changes in the atmosphere and climate of the planet. Upon impact, vaporized dirt and rock would fill the atmosphere, blocking sunlight and creating a state of near-permanent darkness and winter-like conditions.
The impact of an asteroid with Earth can cause massive destruction. Climatic and atmospheric change, as well as the damage on the ozone layer, are some major result of the impact. Darkness will surround the earth, blocking the sunlight with a winter-like environment. Greenhouses released from the impact will increase the temperature after the particles settle down in the atmosphere.
